iobuf: Increase the size of the buffer. Add iobuf_set_buffer_size.
* common/iobuf.c (IOBUF_BUFFER_SIZE): Rename to
DEFAULT_IOBUF_BUFFER_SIZE and increase to 64k.
(iobuf_buffer_size): New var.  Always use this instead of the macro.

(struct file_filter_ctx_t): Add field delayed_rc.
(file_filter) [!W32]: Try to fill the supplied buffer.

I did some test to see whether this has an effect.  A test program
piped 100 million random bytes to gpg to symmetric encryption only w/0
compression.  Single read means the old behaviour, multi read the new
behaviour which fills up the buffer when the read(2) returned only 4k
in once call.

Does not make much of a difference :-(.  Maybe it changes depending on
the type of used filters.

--

This code has seen only a very few manual tests.  Encrypting always
uses a 64k chunks and decryption has not been tested with larger
chunks.  Those small chunks make debugging much faster.

Tests can be done using:

  gpg --rfc4880bis --pinentry-mode=loopback --passphrase abc \
      --force-aead --aead-algo ocb --s2k-mode 0 --cipher AES \
      -v -z 0 --status-fd 2 -c <INFILE >OUTFILE

kbx: Simplify by removing custom memory functions.

(return_null_if_fail): Ditto.
(return_val_if_fail): Ditto.
(never_reached): Ditto.
--

Originally the KBX code was written to allow standalone use.  However
this required lot of ugliness like separate memory allocators and
such.  It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier.  Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions.  This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

common: Use larger buffer for homedir in case of 64 bit UIDs.
* common/homedir.c (_gnupg_socketdir_internal): Enlarge PREFIX by 6
bytes for "/gnupg".
--

The temporary buffer was to short for the extra "/gnupg".  However the
20 bytes for the UID is large enough for all 32 bit UIDs and would
only fail (detected) if  a 64 bit UID is used.

build: Do not define logging.h constants for libgpg-error dev versions.
* common/logging.h [GPGRT_LOG_WITH_PREFIX]: Do not define the log
constants.
--

logging.h uses constants we plan to use for future versions of
libgpg-error.  My dev version already has the logging functions and
thus I run into a conflict.  This patch protects against this and make
the GnuPG work with later libgpg-error versions.

It was not the best idea to use constants from a planned libgpg-error
in the first place.  The actual problem are the enums, the macros
won't harm.

Use the gpgrt log functions if possible.
* common/logging.c: Do not build any code if we can use the gpgrt_log
functions.
(log_logv_with_prefix): Rename to log_logv_prefix and change order of
args so that this function matches its printf like counterpart
gpgrt_logv_prefix.  Change all callers.
(log_debug_with_string): Rename to log_debug_string. Change all
callers.
(log_printhex): Move first arg to end so that this function matches
its printf like counterpart gpgrt_log_printhex.  Change all callers.
* common/logging.h: Divert to gpgrt/libgpg-error if we can use the
gpgrt_log functions.
(bug_at): Add inline versions if we can use the gpgrt_log functions.
* configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM.
(mycflags): Add -Wno-format-zero-length.
--

This patch enables the use of the log function from libgpgrt (aka
libgpg-error).  Instead of checking a version number, we enable them
depending on macros set by recent gpg-error versions.  Eventually the
whole divert stuff can be removed.

The -Wno-format-zero-length is required because log_printhex can be
called with an empty format string.  Note that this is fully specified
standard C behaviour.

--

Without the rounding we saw in verbose mose

immediately without the expected one second delay.  Waiting for the
next seconds did not work if nanosleep was used due to improper passed
parameters in gnupg_usleep.

Adding --debug-wait for dirmngr in daemon mode is required to test
this change.

Under Windows we need to check that the Jitter RNG is active in de-vs
mode.  Under Linux this is not necessary because /dev/random can be

The assert could have lead to a regression for no good reason.  Not

Our regression test suite makes use of the envvar GNUPG_BUILDDIR.  Now
the code in gnupg for evaluating this envvar is only included in a
development version (that is one with a "-betaNNN" suffix).  For a
real release the envvar is not considered.  However during a "make
distcheck" a "make check" is done for the build directory.  Without
defining that envar we would try to run binaries in the install
directory ("_inst" sub-directory) which are not yet installed at that
time.

Consider a situation where the user passes "--status-fd 3" but file
descriptor 3 is not open.

During the course of executing the rest of the commands, it's possible
that gpg itself will open some files, and file descriptor 3 will get
allocated.

In this situation, the status information will be appended directly to
whatever file happens to have landed on fd 3 (the trustdb? the
keyring?).

This is a potential data destruction issue for all writable file
descriptor options:

   --status-fd
   --attribute-fd
   --logger-fd

It's also a potential issue for readable file descriptor options, but
the risk is merely weird behavior, and not data corruption:

   --override-session-key-fd
   --passphrase-fd
   --command-fd

Fixes this by checking whether the fd is valid early on before using
it.

This patch allows the user to modify the behavior of the

time in GnuPG will be frozen at the specified time, instead of

If two struct ARGPARSE_OPTS share a prefix in their long_opt name, but
